You spend a third of your life sleeping, give or take, and sometimes the way you sleep can lead to chronic back pain.

The cure for that pain could be getting rid of an old, worn-out mattress, doubling (or tripling) down on pillows, or getting off the couch and walking around the block.

Those are a few of the potential cures recommended by Dr. David E. Fish, a medical doctor on staff with the UCLA Spine Center with a master’s degree in public health, who has partnered with mattress retailer Sit ‘n Sleep — you know, the “We’ll beat any advertised price or your mattress is FREEEEEEEE!!!”/”You’re KILLING me Larry!!!” people — to spread the word about not just buying new beds but doing all you can for a healthy, pain-free back.
